FCC telemarketing laws include those statutes and regulations which are interpreted and enforced by the Federal Communications Commission. The most well known FCC telemarketing law is the Telephone Consumer Protection Act (TCPA). The TCPA is a harsh law, containing numerous technical and behavioral rules and prohibitions for call centers, sellers and debt collectors. For example, the FCC's TCPA telemarketing laws prohibit autodialing cell phones for marketing purposes without prior express written consent. Even non-marketing automated calls to cell phones require at least "express consent" (but not written). The FCC can fine companies up to $16,000 per violation. Private citizens can also sue companies directly under the FCC's telemarketing laws for up to $1,500 per call.
